“Pull down the Notifier menu (either Calendar or Gmail), hold down Command and Option, and click Preferences on the menu. You’ll see a hidden settings editor. Enter ‘SecureAlways’ in the Key field (upper and lower case must be entered as shown) and 1 in the Value field, then click Set. Quit Notifier and start it up again. From now on all connections with both Gmail & Gcal will be https. Enjah”
